NASA Launch Director Tim Dunn gives the final ‘go’ for the agency’s Imaging X-Ray Polarimetry Explorer (IXPE) launch!
The Kennedy Space Center skies soon will be lit up as the Falcon 9 rocket fires up to launch the mission into space.
Everything is looking great as NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft, aboard a SpaceX Falcon 9 rocket, prepares to launch into the sky from NASA’s Kennedy Space Center in Florida. We are now just about 5 minutes away from liftoff.
NASA Launch Director Tim Dunn reported the rocket is on internal power and it is ready to launch. Stage 1 launch load is complete.
In just about 10 minutes, the Falcon 9 rocket’s nine Merlin engines will roar to life, sending SpaceX’s Falcon 9 rocket and NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft into space. The rocket has been fueled with liquid oxygen and RP-1 – rocket-grade kerosene. The Falcon 9’s engines are chilling in preparation for launch.
Excitement is building as IXPE, NASA’s first dedicated mission to measuring X-ray polarization, nears launch. IXPE will study changes in the polarization of X-ray light through some of the universe’s most extreme sources, including black holes, dead stars known as pulsars, and more.
The weather outlook for NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) launch from Kennedy Space Center remains outstanding. Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a greater than 90% chance of favorable conditions for liftoff of NASA’s first dedicated mission to measuring X-ray polarization.
Propellant load is underway, which eliminates IXPE’s 90-minute launch window.
“We have committed to this and we are committed to a T-zero at 1 a.m.,” said Mic Woltman of NASA Communications.

IXPE’s launch from NASA’s Kennedy Space Center in Florida is now about 40 minutes away. Coverage of launch day activities will continue here on the blog. Also, tune in to NASA Television, the NASA app, or the agency’s website, starting at 12:30 a.m. EST for a live broadcast. Liftoff, from Kennedy’s Launch Complex 39A, is targeted for 1 a.m.
The weather outlook for today’s early morning launch of NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft from Kennedy Space Center is terrific. Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 90% chance of favorable conditions for liftoff, with the cumulus cloud rule serving as the primary weather concern.
A collaboration between NASA and the Italian Space Agency, IXPE is NASA’s first mission dedicated to measuring X-ray polarization. Launch, which is managed by NASA’s Launch Services Program, based at Kennedy, is targeted for 1 a.m. EST from the Florida spaceport’s Launch Complex 39A.

NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) mission sounds cool, and even has a catchy name. But what is IXPE’s goal and how did the project come about? Here is a more in-depth look at IXPE, NASA’s first satellite dedicated to measuring X-ray polarization.
IXPE is going to explore some of the most extreme and mysterious objects in the universe – including black holes and pulsars – and the X-rays they emit. It is the first mission that will map the polarization of many of these objects.
IXPE carries three state-of-the-art space telescopes with special polarization-sensitive detectors. Polarization is a property of light that holds clues to the environment from which the light originates. By providing the first-ever dedicated look at polarized X-rays, IXPE will help us discover the secrets of some of the most extreme cosmic objects of the universe: the remnants of supernova explosions, neutron stars and black holes in our galaxy, and super massive black holes at the centers of galaxies.
NASA selected IXPE as a Small Explorer mission in 2017. The IXPE project is a collaboration between NASA and the Italian Space Agency. NASA’s Marshall Space Flight Center in Huntsville, Alabama manages the IXPE mission. Ball Aerospace, headquartered in Broomfield, Colorado, manages spacecraft operations with support from the University of Colorado at Boulder.
NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Explorers Program for the agency’s Science Mission Directorate in Washington.
